  • Only one specimen of this species was available for study; more specimens are needed in order to gain a more complete picture. A notable characteristic of this specimen is that the apices of the bracts do not overlap with the base of the bract distal to them. The height was not recorded on the specimen label, but it is likely from the other measurements taken that this species is smaller than the other species and the specimen seen was more slender than any of the other specimens of the genus. According to the specimen label, the flowers are light green and the fruit is green. (Hastings, L. 2003: A Revision of Rhapis, the Lady Palms)A
